The first thing that stood out to me about this book was its worldbuilding, showing one of the harshest parts of the exalted setting and how the people there built their lives, traditions and customs, and what happens when all those things are put in danger. The characters both Mortal and Exalted are compelling, and the author successfully weaves their differing perspectives into gripping drama throughout the story. You will care about these people by the end of this book.
While the worldbuilding and characters are the strongest part of the book, the action can sometimes come off as oddly paced, and the quick switching between perspectives can be unduly disorienting during fast-paced scenes, leaving you scrambling to place yourself in time and space for the first couple paragraphs after a switch, in addition some of the descriptions got a tad repetitive at times(prepare for a lot of mentions of inner fire). This does mean the latter part of the story feels a bit weaker than the earlier chapters, but by that point I was invested enough in the characters and their struggles to keep reading right through to the end.
All in all, a welcome addition to the world of Exalted, and a solid tale of adventure and friendship at the frigid edges of Creation.
